COTTON-SEED-DELINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 481,416, dated. August23, 1892.

Application filed October 16, 1891. $erial No. 408,948. (No model.)

To 0. whom it may concern:

Be it known that I, JOHN HOWARD McGoR- MICK, a citizen of the UnitedStates, residing at New Orleans,in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements in Cotton-Seed-Delinting Machines; and I do declare the following to be a full,clear, and exact description of 'the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in cotton-seed-delintingmachines, and the novelty will be fully understood from the followingdescription and claims when taken in connection with the annexeddrawings; and the objects of my invention are to remove all lintremaining upon cotton-seed after the ordinary ginning process. I attainthese objects by the mechanism illustrated in the accompanying drawings,in which- Figure 1 is a sectional side view of a machine embodying myinvention. Fig. 2 is a top View of the shaking-sieve. Fig. 3 is a sideview of the brush-cylinder. Fig. 4c is a perspective view of a brushstave or lag. Fig. 5 is a side View of the dust and fan chambers; also,of the dust, seed, and lint discharge outlets. Fig. 6 is a cross-sectionof the delinter. Fig. 7 is a top view of the metal plate on top of thebrush-cylinder, provided with blades for distributing cotton-seed. Fig.8 is a sectional side view of the perforated and indented casing. Fig. 9is an edge view of the indented and perforated casing.

Similar letters and figures refer to similar parts throughout theseveral views.

In the drawings, A A represent legs which support the machine; B, anouter frame,which may be of Wood or metal.

0 is a shaft, to which is attached a brushcylinder D, the brushes onsaid cylinder being of wire and each wire being driven into the woodenstave or lag, thus giving greater strength to the said wire, thusobviating the necessity of a leather backing for the wire brushes asheretofore used.

F are arms of the brush-cylinder.

G is a metal plate which forms the top of the brush-cylinder and uponwhich seed from hopper Z fall, said plate being provided with metalblades, as shown in Fig. 8, and which throw the seed between cylinder Dand its perforated and indented casing E and forms a draft downwardbetween the brush and cats in g. OylinderD is also provided with a brushH, which. prevents accumulation of seed at the bottom of the cylinderand forces the same downward through chute S. (Shown in Fig. 1.)

L is a driving-pulley.

M is a step in which the shaft O rests.

O is a grooved cam on the shaft, to which cam one end of an agitator Pis attached, while the opposite end of said agitator is attached to aninclined sieve Q, and as the shaft O is rotated a vibratory movement asgiven to the perforated shaker Q by means of the agitator]? and groovedcam 0, thus enabling all dust in the cleaned seed as they descendthrough the chute S to fall into a chute U, where it remains until asufficient quantity is collected to be discharged by its own gravitythrough a trap-door R, which is caused to open by the weight of theaccumulated dust. The step M is provided with a threaded exteriorsurface, which is indicated by T and which enables the shaft 0 to beraised or lowered by simply screwing the top in one direction oranother.

V is a discharge-outlet for the lint.

IV is a lint-chamber.

X is an air-inlet provided with a door not shown.

Y is an opening in return-lint chamber 4 and through which all lint thatmay descend to its lower opening will be driven by the blast from a fanK in the direction indicated by arrows in chamber 4, and thence throughY back into chamber IV, where it is drawn into the fan-chamber, thendischarged through the chute V. The hopper Z is provided with a cylinderor roller 1, studded in such a manner as to discharge upon G and at sametime prevent all choking of seed in the throat of the hopper, saidcylinder or roller 1 is provided with a pulley 2, over which a beltpasses and engages a pulley 3 on shaft G.

In practice the machine is put in motion by passing a belt over thedriving-pulley L, the belt being connected to an engine or other motornot shown. The shaft O as it rotates also rotates pulley 3 and thecylinder or roller 1 within the hopper, and the cotton-seed are fed fromthe hopper upon the plate G, the blades on the periphery thereofthrowing the cotton-seed between the brush-cylinder D, which is beingrotated by the shaft and the stationary perforated and indented metalcasing E. As the seed descend the ends of the bristles of thebrush-cylinder D, which is being rapidly rotated, come in contact withthe lint upon the seed and remove the same by impinging the seed againstindentations of metal casing, and as the lint is removed the current ofair caused by the rotation of the cylinder D drives the lint through theperforated openings into the chamber W, and the fan K draws the lint outof the chamber W and blows it out through chute V, while the seeddescend through chuteS, the bottom of said chute being perforated andmade to vibrate by means of agitator P, which receives its motion fromshaft 0. The brush being spiral in shape enables the seed to descend,prevents all choking, and gives a large increase in the capacity of themachine. The end of the shaft 0, resting in the movable step, isconcave, and revolveson a metal point which forms part of the step.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a cotton-seed delinter, the combination, with the frame B, of theindented and perforated casing arranged thereon andforming alint-chamber, the brush-cylinder arranged within the indented casing,the vertically-adjustable shaft secured to said brushcylinder, thefan-casing below the brush-cylinder, the fan arranged therein andsecured to said shaft, the chute leading from the interior of theperforated casing and having a perforated shaker in its bottom, thedust-receiving chute below said shaker, the cam on the shaft, and anagitator for engaging the cam on the shaft for operating the shaker,substantially as specified.

2. Ina cotton-seed delinter, the combination of the casing, the verticalshaft therein, the vertically-adjustable bearing for said shaft, thebrush-cylinder secured to the shaft and provided with a spiral ,brnshonthe periphery, a brush on the bottom of the cylinder, the casing havinga return-inlet for lint and a discharge-outlet for seed, a sievearranged in the seed discharge or outlet, and an agitator for said sieveconnected with the shaft, substantially as specified.

3. A cotton-seed delinter having the following instrumentalities incombination: a lint-chamber arranged upon a suitable frame, a fan-casingarranged below the lint-chamber and in comm nnication therewith, alintdischarge leading from said casing, a perforated casing arranged inthe lint-chamber, a

vertically-adjustable shaft passing through.

the respective chambers, the brush-cylinder secured to the shaft, abrush secured to the under side of the brush-cylinder, a fan alsosecured to said shaft, a grooved cam secured to the shaft below thefan-casing, a sieve arranged on the seed-discharge, a dust-chamberbeneath the sieve, and an agitator connecting the sieve with the cam onthe vertical shaft, alldadapted to operate substantially as specifie Intestimony whereof I affix my sigpature in presence of two witnesses.
